Required Methods§

Source

fn step_forward(&self) -> Self

Advance a timestamp by the least amount possible such that ts.less_than(ts.step_forward()) is true. Panic if unable to do so.

Source

fn step_forward_by(&self, amount: &Self) -> Self

Advance a timestamp forward by the given amount. Panic if unable to do so.

Source

fn try_step_forward_by(&self, amount: &Self) -> Option<Self>

Advance a timestamp forward by the given amount. Return None if unable to do so.

Source

fn try_step_forward(&self) -> Option<Self>

Advance a timestamp by the least amount possible such that ts.less_than(ts.step_forward()) is true. Return None if unable to do so.

Source

fn step_back(&self) -> Option<Self>

Retreat a timestamp by the least amount possible such that ts.step_back().unwrap().less_than(ts) is true. Return None if unable, which must only happen if the timestamp is Timestamp::minimum().
